IANAL but I gather from friends who work in compliance, that reimplementation more or less effectively shields you from "copyright" claims on code. As a result it sure seems like Copilot or similar applications of DL/ML is a red herring a general criticism. If someone is upset their elegant solution to a specific problem is being replicated, that's not about DL/ML; and there are unlimited opportunities for reverse engineering or reimplementing or transforming or rewriting or whatever you like, which affect the same algorithm etc. If you want a software patent, take up the fight in that domain. If you don't want people reusing your logic, don't put it in public view or for that matter anywhere an interested and motivated party might disassemble or deobfuscate it.
